You all have some excellent test bench setups! I have been interested in setting up a test bench for a while, and was unsure how exactly to go about doing so, until I stumbled on the JimStim info in the TunerPro thread. It is great that there is such a tool available, and I plan to not only use it to verify ECU repair work, but also use it to try to further modify and verify code modifications.

Before I learned of the JimStim, I was planning to use a spare engine wiring harness and some sort of multiple DC voltage power supply, and who knows what else, to create a test bench of sorts. Hell, I even though of using a battery operated Tens Unit to create electrical pulses to mimic the sensors that use those types of signals.

For those of you using batteries for power supply, have any of you tried using the power supply listed as an accessory?
